A point mutation or covalent modification in bacterial chemotaxis receptors causes bacteria to be repelled by attractants, and attracted to repellents. The variety of conditions causing inverse responses suggest that the signal transduction mechanism in receptors can be readily rewired to elicit inverse responses. A model is presented in which the orientation of a critical residue with respect to an active site determines whether the receptor produces normal or inverted signals. The model is… CONTINUE READING
